Time synchronization of electronic shelf labels

Abstract

In some aspects, an electronic shelf label (ESL) may receive, from an access point (AP), baseline timing information including a baseline time and a baseline event counter value that are associated with a first periodic advertising broadcast. The ESL may receive, from the AP, a second periodic advertising broadcast including an indication of an event counter value associated with the second periodic advertising broadcast. The ESL may calculate a local time of the ESL based at least in part on the baseline time, the baseline event counter value, and the event counter value associated with the second periodic advertising broadcast. Numerous other aspects are described.
